Currently, the font specification calls `Georgia` as the primary serif font for question titles. While undeniably an attractive font, its zero renders almost exactly the same as a lower case letter 'o'. This introduces a significant level of ambiguity:

![Georgia rendering a zero][1]

While I think it extremely unlikely that there is a serif font that is readily available on most Unix user's machines that would have a slashed or dotted zero (the ideal), with only a small tweak to the CSS, it would be possible to improve the rendering of zeros _for most users_:

![Times as the default][2]

I'm reluctant to suggest a significant change as I think the overall look of the site is extremely professional - however, for a site for coders and geeks, having ambiguous zeros is rather unfortunate[1].

With only a small change to the stylesheet, this can be improved. From:

 #question-header .question-hyperlink {
 color: #155078;
 font-family: Georgia,"Times New Roman",Times,serif;
 font-size: 24px;
 ...
 }

to:

 #question-header .question-hyperlink {
 color: #155078;
 font-family: "Times New Roman",Times,serif;
 font-size: 28px;
 ...
 }

Is this something that others are similarly exercised about? Could it be considered for a change?
